What kind of Algae is this? Help.

Hello, I need someone's input. Been reef keeping a while now. But this is the first time I encountered this algae. The tank is a 155g shallow including the sump. It'sbeen up for about 2 months now. I know that diatoms are a thing for new tanks but this is the first time I saw this. it looks like a string. Any idea guys?

You are welcome. Try to get a sample under the microscope, that will tell you how to best treat.

How's your nutrients? Dino's like when the po4 is zero. I would test and if you find a zero get that number up and off zero.

I'm out of town at the moment. As soon as I get back I will test for Phos and keep you guys posted

Ok guys I'm back. The "Dino" is gone after i dosed hydrogen peroxide. My tank is a 155g so I dosed 1ml per 10 gallons volume 10= 3%. Literally 85% of the dino is gone. I'm going to dose again today and hopefully it will be gone by tomorrow.

Oh BTW. First picture is the tank with Dino the rest are my other two tanks.

Params of the tank with dino.
Nitrate 20ppm
Phos 1ppm "API test kit"

Alk 9
Cal 440
Mag 1400
